The weight of the human prostate.

The weight of the prostate proper was determined in an autopsy series comprising 205 cases. The dissection technique of Tisell & Salander made it possible to delimit the prostate proper from non-prostatic tissue. The mean weight of the "normal" prostate in adult men was about 11 grams (range 7--16). This weight as well as the water content did no change with age. Individuals who died after protracted disease had lower prostatic weight. The presence of periurethral adenomas was associated with a higher weight of the prostate proper.
